PAIL-EAR.

SPECIFICATION forming part of Letters Patent No. 329,231, dated October27, 1885.

Application filed June 18, 1884. Serial No. 135,234. (No model.)

To all whom it may concern:

Be it known that we, JAMES SPRUCE and ASA M. CoMsTooK, of Waterbury, inthe county of New Haven and State of Connecticut, have invented a newImprovement in Pail-Ears; and we do hereby declare the following, whentaken in connection with accompanying drawings and the letters ofreference marked thereon, to be a full, clear, and

to exact description of the same, and which said drawings constitutepart of this specification, and represent, in-

Figure 1, an outside view; Fig. 2, an inside view, Fig. 3, alongitudinal central section;

1 Figs. 4 and 5, modifications.

This invention relates to an improvement in the article of manufacturecommonly called pail-earsthat is to say, the metal socket which isattached to pails, and into which the ends of the bail are introduced asbearings.

in which the bail will swing.

In the more general construction of this class of ears they are struckfrom sheet metal, and in outline, as seen in Fig. 1, it being a I 2 5cup-shaped center, with a flange extending to the right and left, as ameans for securing the ear to the pail. In the center of the cupshapedportion is a holeto receive the end of the bail-wire. The hole in thecup has 0 usually been made by a simple perforation through the bottomof the cup, presenting the edge of the metal to the wire of the bail,and thus giving only the thickness of the metal as a wearing-surface,and unless the 3 5 metal be very thick and stout the metal surroundingthe hole frequently tears out, so as to permit the end of the bail toescape, and as new ears are not generally accessible to those who usethe pails, it is practically impossible 0 to properly repair the pail bythe application of a new ear.

The object of our invention is to construct the car so as to present alarger bearing-surface for the bail, as well as greatly strengthen themetal around the bearing; and it consists in the construction of theear, as hereinafter described, and more particularly recited in theclaims.

A represents the cup shaped center; B B,

the projections therefrom, by which the ear is secured. The cup-shapedportion is made substantially concavo-convex, as seen in Fig.

3. Instead of cutting away the metal to form thehole, as heretoforepracticed, we turn the metal inward, as seen at a, Fig. 3, to form aninwardly-projecting tube. Around this tube awire ring, I), is set, andthen the metal which has been turned inward is struck down over thering, and so as to substantially inclose it and firmly attach it to thecup around the hole, and thus form a bearing of considerable thickness,presenting a rounded surface, and strengthened not only by the peculiarshape of the metal turned in, but also by the Wire ring introduced.

Instead of introducing a wire ring around the hole, the metal may berolled upon itself, as seen in Fig. 4, forming a metal bead from themetal itself around the opening, and of substantially the same shape asif a wire were introduced; 01', as seen in' Fig. 5, instead of turningthe metal inward to form the bead around the hole, there may be aflanged tube like an eyelet introduced through the opening, the flangeupon the outside, the inner end 7 turned outward and over the Wire ringI). In any case a smooth rounded surface-bearing is formed, so farstrengthening the metal about thehole that theliability to ruptureisavoided, and a much lighter metal may be employed than in the usualconstruction.

We claim-- 1. As an article of manufacture, a pail-ear made from sheetmetal, consisting of the cupshaped center A, with projections 13therefrom to secure the ear to the pail, the center pierced to formabearing for the bail, the bearing re-enforced by the metal turned infrom the hole upon the surface of the cup, so as to form a bead aroundthe bearing, substano tially as described.

2.. A pail-ear made from sheet metal, consisting of the cupshaped centerA and projections B therefrom, the center pierced to form the bearing,combined with a ring, b, around 5 the bearing, the metal being turnedover the wire to inclose and secureit in place, substan- .tially asdescribed.
